Standard order of planets from the Sun

Steps:

• Recall the inner planets: Mercury closest, then Venus, Earth, Mars.
• Add outer planets: Jupiter, Saturn, Uranus, Neptune farthest.
• Compare choices to this sequence: Mercury-Venus-Earth-Mars-Jupiter-Saturn-Uranus-Neptune.
• Identify the matching option.

Why C is correct:

• It lists planets in the exact sequence of increasing heliocentric distance, per astronomical classification.

Why the others are wrong:

• A starts with Venus before Mercury, swapping inner order.
• B places Mars before Venus and Earth, disrupting inner sequence.
• D mixes Mars and Venus before Earth, and swaps Saturn-Jupiter.

Final answer: C
